Use the following scenario to answer questions 1-2: During a clinical rotation on the medical-surgical floor of a hospital, you notice several patients have developed urinary tract infections (UTIs... ) associated with their Foley catheters (tubes inserted into the bladder to drain urine). Your staff physician agrees that this is a problem and offers to help with an improvement project. Together, you work through several PDSA cycles to reduce the rate of UTIs on your floor. Which of the following methods would you recommend to display your improvement data? (A) Draw a bar chart. (B) Write a list of numbers. (C) Create a two-column table. (D) Draw a run chart. - ANS -D Run charts are an effective way to view changes over time. They are much easier to interpret visually than a list of numbers or a static display of data such as a bar chart. When designing the run chart, it is important to include: (A) Units of time on the Y axis (B) The rate of UTIs on the X axis (C) Units of time on the X axis (D) A and B - ANS -C The run chart should display units of time — whether it's days, weeks, or months — on the X axis. The Y axis is where you plot the key variable you are measuring, which in this case is the rate of UTIs. What is the minimum number of data points you should usually have to look for signs of improvement on a run chart? (A) 6 (B) 10 (C) 15 (D) 25 - ANS -B A run chart becomes more powerful as you add more data points because there will be more opportunities to identify patterns. If you're looking for signs of improvement, usually you need at least 10 data points. Which of the following is a problem with static data? [Show More]
